Duplex Ultrasound Scan
What is the test?
A duplex ultrasound scan is a noninvasive
examination that uses color Doppler technology. Harmless high frequency sound
waves bounce off of the body's internal structures and are processed
electronically to yield information about blood flow and the condition of the
arteries and veins. A duplex ultrasound is painless, there is no radiation
involved, and there are no risks known to be associated with its use. This test
is typically used to diagnose suspected artery disease and other vascular
How do I prepare?
Please plan to arrive at your designated
Imaging Services site 15 minutes prior to your scheduled appointment. There is
no specific preparation for a duplex ultrasound scan of blood vessels in the
arms, legs, and neck. It is best to wear loose-fitting clothing. If you are
having a study of the blood vessels in your arms, we recommend wearing a tank
top that exposes your shoulders, neck, and arms.
An ultrasound of the abdominal arteries and
veins requires that you have nothing to eat or drink after your evening meal
the night before your ultrasound. You may take your regular medicine with a
small amount of water. Be sure to bring a list of your current medications with
you when you come to the medical center for your test.
What can I expect during the
You may be asked to change into a gown,
depending on the specific exam. You will be asked to lie on an examining table
for 30 to 60 minutes. The vascular technician will apply some cool, clear gel
to your skin. During the exam, an ultrasound transducer (which looks like a
wand) will be moved lightly up and down your skin where the gel has been
applied. Images created from the sound waves will appear on a video monitor.
The sounds and images of blood moving through the vessels are saved in the
computer for analysis by a vascular specialist.
How and when will I get my test
Typically, within 48 hours a written report
of your test results will be sent to your referring physician, who will review
them with you. Additional time (3 to 5 days) may be required if we are
comparing these test results to previous findings from another hospital.
